Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the stability of the milk system when adding exogenous calcium in liquid dairy products in the prior art, and the resulting product has a thick mouthfeel and bad flavor (astringent, salty, bitter, etc.) ), and only focus on adding calcium ions blindly to the product, while ignoring the absorption of calcium ions, the strengthening of bone matrix, the increase in the number and activity of osteoblasts and osteoclasts, and the protection of cartilage tissue, but not fundamentally In order to solve the defects of how to increase calcium ions in the human body and promote the growth of bone tissue, a new liquid milk and its preparation method are provided

[0059] raw material:

[0060]

[0061]

[0062] Preparation Process:

[0063] (1) The raw milk is concentrated by falling film at low temperature to increase moisture to obtain concentrated milk, wherein the concentration temperature is 50°C, and the concentration pressure is 10000Pa;

[0064] (2) Mix the concentrated milk with hydrolyzed egg yolk powder, hydrolyzed collagen, casein phosphopeptide and vitamin D. When mixing, the stirring speed is 20rpm, and the stirring time is 10min. The protein and fat are standardized, and the standardized protein Content 3.9%, fat content 0.4%; then stir evenly;

[0065] (3) Two-stage homogenization: the homogenization temperature is 70°C, the first-stage homogenization pressure is 23MPa, and the second-stage homogenization pressure is 10MPa;

[0066] (4) Sterilization: the sterilization condition is 120°C, and the time is 15 seconds;

[0067] (5) After cooling to 2-6°C, fill it.

Abstract

The invention discloses liquid milk and a preparation method of the liquid milk. The liquid milk comprises, by weight, 99.149996%-99.799999% of concentrated milk, 0.05%-0.2% of hydrolyzed egg yolk powder, 0.1%-0.5% of hydrolyzed collagen, 0.05%-0.15% of casein phosphopeptide and 0.000001%-0.000004% of vitamin D. The preparation method of the concentrated milk includes the step of enabling raw milk to be concentrated under the condition of 40DEG C-60DEG C and 10000Pa-20000Pa until the calcium content is 120-150mg / 100mL. According to the preparation method of the liquid milk, the quality of the liquid milk is improved, the calcium content in the milk is improved, and the liquid milk is safe, comprehensive in nutrition, good in stability, high in calcium content and balanced in calcium-phosphate proportion. Calcium ion absorption, bone matrix strengthening, increase of the numbers of osteoblast and osteoclast, the improvement on the activity of the osteoblast and the osteoclast and cartilage tissue protection are taken into consideration, and the liquid milk is good in mouthfeel and taste and can be easily digested and absorbed by human bodies.

Description

technical field [0001] The invention relates to a liquid milk and a preparation method thereof. Background technique [0002] Osteoporosis is a common and frequently-occurring disease among women and middle-aged and elderly people. my country is the country with the largest elderly population in the world. There are about 90 million osteoporosis patients, accounting for 7.1% of the total population. The "Asian Audit Report" issued by the International Osteoporosis Foundation shows that by 2020, China's osteoporosis Or patients with bone loss will increase to 286.6 million people, which means that about 1 out of 5 Chinese people have bones that are not hard enough. Osteoporosis can cause complications such as bone pain and shortened limbs. The most serious consequence of osteoporosis is fracture, which has slow healing speed and many complications. Among them, the mortality rate of hip fracture patients within one year after operation reaches 20%. Therefore, osteoporosis is ...
